Product Overview
Microporous Ceramic Membrane Technology for Mining Slurry Dewatering
The Disc Compact Sector Plate is a precision-engineered alumina ceramic membrane filter plate manufactured using advanced inorganic membrane preparation processes. The plate body is composed of countless uniformly distributed micropores with diameters ranging from 0.5 to 5 micrometres, forming a highly consistent filtration matrix suited to high-throughput mining slurry dewatering and mineral concentrate filtration.
When pressurised slurry passes through the filter disc, mineral particles are retained on the ceramic membrane surface while filtrate passes freely through the micropore network. This mechanism delivers reliable concentrate dewatering and tailings dewatering performance across iron ore, copper, gold, lithium and other mineral processing applications -- producing low-moisture filter cake and high-quality recovered process water.
Manufactured via integral forming and whole-body sintering, the plates exhibit exceptional mechanical strength and dimensional stability. Under operating fluid pressure, micropores maintain their geometry without deformation -- enabling consistent vacuum ceramic filter efficiency and predictable cycle performance over an extended service life.

Manufacturing Excellence
Integral Forming & Whole-Body Sintering
Our Disc Compact Sector Plates are produced through a fully controlled manufacturing sequence combining advanced water-casting, integral forming and high-temperature whole-body sintering -- the same process employed for our provincial key new-materials programme with an annual production capacity of 400,000 ceramic filter plates. This process ensures every disc filter plate meets the dimensional and performance tolerances required for drop-in replacement across all major vacuum ceramic filter machine configurations.
-
Raw Material Preparation
High-purity alumina powder blended with proprietary micropore-forming agents and binders, formulated in collaboration with Shandong University of Technology New Materials Laboratory to optimise pore structure for mining filtration performance.
-
Advanced Water-Casting & Integral Forming
Precision water-casting process ensures homogeneous slurry distribution and consistent green-body density, establishing the foundation for uniform pore structure throughout the ceramic filter disc cross-section.
-
High-Temperature Whole-Body Sintering
Controlled sintering in high-temperature kilns bonds alumina crystals into a monolithic structure, achieving high mechanical strength, dimensional stability and the target 0.5-5 μm micropore distribution required for efficient tailings dewatering and concentrate filtration.
-
Physicochemical Testing & Quality Control
Each batch undergoes dimensional inspection, water permeability measurement, back-flush pressure testing and structural integrity assessment in our in-house physicochemical testing laboratory before shipment as ceramic filter spare parts.
Applications
Proven Across Mineral Processing & Tailings Dewatering
Disc Compact Sector Plates are deployed in vacuum ceramic disc filter machines for concentrate dewatering, tailings dewatering and mining water treatment across a broad range of mineral processing and metallurgical operations globally.
Iron Ore
Concentrate dewatering in magnetite and hematite processing circuits, delivering low cake moisture for downstream pelletising or direct shipping. High-volume iron ore tailings dewatering with excellent water recovery.
Copper & Gold
Flotation concentrate dewatering and tailings management. Ceramic plates resist the mildly acidic and alkaline conditions typical of copper and gold processing -- ideal for copper mine slurry dewatering applications.
Lithium
Spodumene and lithium carbonate slurry dewatering. High chemical inertness prevents contamination of battery-grade lithium products -- a critical requirement for lithium mineral filtration solutions.
Nickel
Nickel sulphide and laterite concentrate dewatering in high-throughput operations. Plates withstand aggressive slurry chemistry without degradation, supporting efficient nickel mining filtration cycles.
Lead & Zinc
Polymetallic flotation concentrate dewatering. Corrosion-resistant alumina ceramic maintains performance in zinc and lead slurry environments, reducing replacement frequency and total cost of ownership.
Tailings Dewatering
High-volume tailings slurry dewatering for water recovery and dry-stack tailings management -- supporting sustainable green mining operations and mining water treatment goals worldwide.

Engineering-Driven Manufacturing
Ceramic Filter Plates Built for the Demands of Modern Mining
Since 2015, we have focused exclusively on the research, development and production of vacuum ceramic filter plates and disc filter spare parts. Our Disc Compact Sector Plates represent the culmination of nearly a decade of process refinement, academic collaboration with Shandong University of Technology's New Materials Laboratory, and field validation across global mining operations -- from iron ore concentrate filtration in Australia to lithium slurry dewatering in South America.
The alumina ceramic membrane in each sector plate is formed through a tightly controlled water-casting and integral sintering sequence that produces a monolithic, crack-free body with a uniform micropore network. This manufacturing consistency -- not achievable with conventional pressing or extrusion -- is the reason our ceramic filters disc plates deliver predictable filtration solutions performance from the first cycle to the last, making them the preferred choice for mines seeking to reduce total operating cost and improve water recovery.
As a provincial key new-materials project, our facility operates standardised production lines, high-temperature sintering kilns and a dedicated physicochemical testing laboratory. Planned annual output of 400,000 ceramic filter plates supports the supply reliability that mining operations require for critical wear-part procurement -- whether for planned maintenance schedules or emergency replacement of failed vacuum ceramic filter components.
Our goal extends beyond product supply: we partner with mining operations worldwide to improve mining filtration efficiency, reduce operating costs, increase water recovery rates and support the transition to green, sustainable mineral processing -- contributing to responsible mining water treatment and dry-stack tailings management.

Frequently Asked Questions
What are alumina ceramic membrane filter plates used for in mining?
Alumina ceramic membrane filter plates are the core filtration media in vacuum ceramic disc filter machines. They are used for mining slurry dewatering, concentrate dewatering and tailings dewatering across iron ore, copper, gold, lithium, nickel and lead-zinc operations. The microporous alumina structure retains mineral particles while allowing filtrate to pass through, producing a low-moisture filter cake and clean recovered process water.
How do I select the right replacement ceramic filter plate for my vacuum disc filter?
Replacement disc filter plates must match your machine's disc diameter, sector count, plate height, outer arc width, inner base width and water spigot dimensions. Our engineers can confirm compatibility from your machine model, existing plate dimensions or a physical sample. We supply ceramic filter spare parts for all major vacuum ceramic filter machine configurations in 1㎡, 2㎡ and 3㎡ series, as well as custom sizes developed from drawings.
What is the service life of a ceramic filter disc plate compared to polymer alternatives?
High-purity alumina ceramic filter plates typically achieve significantly longer service life than polymer or rubber-coated alternatives, owing to their superior wear resistance, chemical inertness and dimensional stability under cyclic vacuum and back-flush pressure. Actual service life depends on slurry abrasiveness, operating pressure and maintenance practices, but ceramic plates consistently reduce replacement frequency and total operating cost in continuous mining filtration applications.
Can ceramic filter plates improve water recovery in tailings dewatering?
Yes. The uniform micropore structure (0.5-5 μm) of our ceramic filters disc plates enables high water flux and effective back-flush regeneration, resulting in cleaner filtrate and higher water recovery rates. This makes them an important component of mining water treatment and dry-stack tailings management strategies -- supporting green mining and sustainable mineral processing objectives.
